What do our customers in London think of our drainage services?

Blocked drain chamber - water pooling on back terrace

We have used this company before and knew the chap who came out previously was excellent so requested him again (Anthony). He is thorough, highly experienced and puts any jargon into easily understandable language and is looking for solutions rather than the 'head scratching - can't fix this in this visit' approach. Uses the time spent on the premises efficiently and gets the job done with minimum inconvenience and is always good natured and helpful. Would trust him with any major drainage/ plumbing issue and as a consequence Drain detectives would be my 'go to' company.

Drain cleared to unblock toilet

The two young men, who came within a couple of hours after I first rang, were exceptionally polite and careful. They removed their shoes in the house without being asked and worked speedily and efficiently. After trying to clear the blocked toilet, they identified the blockage in the drain outside and cleared it with rods and jetted water. They explained clearly what they were doing in answer to my questions and were cheerful throughout. I thoroughly recommend them.

Are you buying a house or flat in London and require a cctv drain survey to check the condition of the drainage system?

If you are a homebuyer in London who has been advised by their house surveyor to get a pre-purchase drain survey or you need a DRAIN SURVEY to investigate subsidence, rodent problems or bad smells, we can help.

The problem with drains is, because they are hidden away, you can't see the damage caused by any defects. A cracked drain could be LEAKING SEWAGE into the ground and you only notice when you see subsidence.

Our engineers will attend your London property to survey the underground drainage. Our survey team will then carefully STUDY the footage and create a detailed, professional report and site plan using the latest software.

If your drain survey report shows no problems, then you have PEACE OF MIND that your drains are in good condition. If not, you have the evidence to negotiate with the vendor of the property you wish to purchase.

If you are in LONDON and are looking for a pre-purchase CCTV DRAIN SURVEY, please call 020 8168 9981.

Fixed a collapsed pipe and put a sleeve in a second drain

We've worked with many companies during our house project and I can honestly say Drain Detectives are like no other company. They have an amazing work ethic and really put customer satisfaction at the very forefront of their business. We were presented with every new home owners worst nightmare, but they were determined to fix a really difficult drain problem (collapsed drain located in an awkward position). From the company director to the workmen, the whole team were incredible. They were so determined and were very professional and polite. More importantly they completed the job well!
